Abstract
A torso exercise machine includes a seat connected to a frame for supporting a user thereon. An upper body engaging member receives force from an upper body part for exercising the torso. The upper body engaging member is pivotally mountd to the frame for pivotal movement along an eccentric path of travel while generating an instantaneous axis of rotation substantially along the torso and spine of the seated user. The eccentric path of travel of the upper body engaging member is illustrated as being obtained by pivotally mounting the upper body engaging member to the frame by a four-bar linkage. A resistance weight opposes movement of the user while the user exercises. A range limiter is provided to reduce the normal range of back and forth movement of the upper body engaging member.
